Diamond Cut
The term 'Diamond Cut' is used to describe the shape of a diamond and also the make or angles of a diamond. When describing the diamond shape we call this the cut macro and when describing the intricate angles, facets and measurements of a diamond we call this diamond cut micro. So first lets discuss the diamond cut macro or shapes.
Diamond Shapes: many people when asked about the cut talk about the shape of a diamond so it would be incorrect to completely ignore this. Diamonds are cut to retain weight and yield from the rough crystal. When diamonds come from the earth they come in shapes such as dodecahedron, octahedron, flats, macles and many other shapes. The diamontaire looks at the rough diamond and decides what shape will maximise his profits and this is often driven by weight or carat yield. The shapes available to the diamond cutter are almost endless but the main shapes include: Round, Square (Princess), Radiant, Emerald, Asscher, Pear, Marquise, Cushion, Oval and Heart shape. The GIA have technical names for these polished diamond shapes for example a Princess cut diamond is called a square modified brilliant and a Radiant cut diamond is called a cut cornered rectangular modified brilliant. The most popular shape is a round closely followed by a Princess or square diamond. We think all diamond shapes are fantastic so please explore our diamond database and select a diamond that suits you best.
Diamond Cut: recently we all became much more educated with the ability to look up anything online and get instant free information. This transformed the diamond industry in the 1990's to focus more on diamond cut in a micro sense which means making a diamond perform better by shaping it to optimise light return and generate sparkle. The GIA started a cut grade system after 15 years of research in 2006 and this system is the most complete and accurate to date. It relies on a Scientific approach, Practicality for consumers to use it, Comprehensive, acknowledges personal and regional Tastes and Preferences, is Predictive so diamond cutters can achieve a desired cut and accessible for the general public to use, understand and trust. The GIA cut grade system that is reported on the diamond certificates are in this order: Poor, Fair, Good, Very Good and Excellent. Working out a cut grade is a very complex task that includes measuring the angles, facets, % relationships and the all round shaping of a diamond. These measurements include the following: The pavilion, table, girdle, culet, keel, crown and the facet work. The relationships between these parts of the diamond are also considered and laser light tracing equipment is used to callibrate and measure. When buying a GIA certified diamond the hard work has been done for you because this information is summarised by the grades Poor, Fair, Good, Very Good and Excellent. Many years of analysis and study have gone into working out the cut grades so unless you have significant time to spare simply use the grades that are on the GIA diamond certificate rather than trying to work it out - it has been done for you and can be trusted 100%.
At Polished Diamonds we sell mainly Very Good and Excellent cut diamonds that return abundant light, perform the best and sparkle magnificenty. The difference between Very Good cut and Excellent cut is small and bearly noticeable yet the difference between Good to Very Good quite large; we recommend Very Good to Excellent cut.
